Freaking out about PGT-A on my only embryo

We only made one embryo out of 12 eggs, theoretically still kicking here on day 3. I had already signed and paid $$$ for the PGT-A testing before the ER, believing that we were going to have multiple embryos to test, and at the strong urging of my IVF doctor because of my age (40). Now I'm so scared that I did the wrong thing, that I should not have paid or signed for this testing. My clinic will transfer low mosaics but not "high mosaics" or aneuploids, and am now reading about how this is all very controversial and some of those high mosaics could in fact make it. I guess I already contractually signed myself up for this. Just wondered if anyone has any thoughts.
